A new route for synthesizing gallium nitride GaN from gallium oxide Ga 2 O 3 and lithium nitride Li 3 N by milling is proposed in this paper. The milling was performed in a planetary ball mill with uni-size ZrO 2 balls to induce mechanochemical reaction between the starting materials in order to prepare GaN powder. The formation of GaN was confirmed in XRD patterns, and the peak ...
Aug 01, 2013 Synthesis of Ga 2 O 3 nanostructures from GaN powder through high-energy mechanical milling in a planetary ball mill and annealing in nitrogen has been investigated. The employed high-energy milling of GaN powder reduced the particle size to the sub-micron range and made the powder more uniform.
In the present work, high-energy mechanical milling of GaN in a planetary ball mill is used for shortening the milling time in the fabrication of one-dimensional Ga2O3 nanostructures.
